How to open saved files using 'read from text file' function

Hi everyone, I am having a hard time trying to solve the this particular problem ( probably because I am a newb to lanbview ). Anyway , I am able to save the acquired waveforms by using the 'Write to text file' icon. I did manually modify the block diagram of the 'Write to text file' icon and create the correct number of connector so as to make my program work. But now I have no idea on how to modify the block diagram of the 'Read from text file' block diagram to make my program 'open' my saved waveforms. Or i do not have to modify anything from the block diagram of the 'Read from text file'? Can anyone teach/help me connect up? Do i need the build array on the "open" page?

What is your LabVIEW version. In all recent version "write to text file" in not something you can modify. Your modification was very misguided and shows very poor understanding of LabVIEW and dataflow. (e.g. Why is the orange array terminal inside the loop? Why is array to spreadsheet string inside the loop? Why do you loop multiple times if you are always writing the same data? Why is there a 500ms delay? That makes no sense even though you added a diagram comment)

You should never modify stock VI. If the connectors don't match, you are using the wrong tools! For example, "write to spreadsheet file" is probably what you want.

Ohmy, thanks altenbach. oh yeah i forgot about those sub VIs. will upload them now. Was rather demoralized after reading the comments and really struck me on how weak i'm at on labview really hope to get this done. But of course i have to study through and see how it works. Actually i am going to replace those 'signal generators sub vi' with ThoughtTechonology's sample code so i can obtain data waveforms real-time using Electrocardiography (ECG) ,Electromyography (EMG ) and Electroencephalography (EEG) hopefully i can find out how to connect the sample code.

( ps . cant connect it now unless my program is working otherwise labview will crash )

( p.s.s the encoder of my biofeedback trainer already acts as an DAQ so i wont need to place an DAQ assistant in my block diagram i suppose )

The sample code of ThoughtTechnology is named as attachment.ashx.vi. too bad i cant use it and present it as my project
